SLOPE/W is the leading slope stability software for soil and rock slopes. SLOPE/W can effectively analyze both simple and complex problems for a variety of slip surface shapes,

pore-water pressure conditions, soil properties, and loading conditions.

Pore-water pressures can be defined using

piezometric lines, spatial functions, or the results

from other GeoStudio finite element analyses. Values

can be displayed as contours on the geometry to reveal PWP values used

in the analysis.

SLOPE/W’s full-featured capability allows for the stability analysis of natural soil and rock slopes under a variety of conditions including surcharge and seismic loading, pore-water pressure fluctuations in the saturated and unsaturated zone, and more. An extensive material model library and flexible search techniques provide the capacity to handle the most complicated failure mechanisms possible in the field of geotechnical engineering.

SLOPE/W is used worldwide for the design and analysis of hydraulic structures subjected to a variety of natural and anthropogenic forces including flood events, rapid drawdown, earthquake loading, and evolving hydrogeological systems. Comprehensive probabilistic and sensitivity analysis facilitates risk-assessment while integration with SIGMA/W or QUAKE/W allows for sophisticated finite element stability and Newmark deformation analyses.

SLOPE/W is commonly used to assess stability of roadways, rail beds, bridge abutments, and MSE walls both during and after construction. SLOPE/W can analyze stability at each construction stage, including the effects of pore-water pressure changes and interaction with reinforcement.

SLOPE/W includes a broad range of stabilization options for civil, geotechnical, and mining applications, from simple earthen toe berms to complex subsurface drainage and soil-structure techniques. The reinforcement functionality, material model library, and diverse pore water pressure definition can be used together to design even the most sophisticated slope stabilization options.

S E E P / W R E S U LT S I N S L O P E / W

Using SEEP/W finite element pore-water pressures allows SLOPE/W to consider complex saturated /

unsaturated pore water pressures. Transient SEEP/W pore-water

pressures can be used to investigate stability changes over time.

S I G M A / W S T R E S S E S I N S L O P E / W

Many geotechnical problems require both deformation and

stability analyses. For others, a limit equilibrium analysis alone is inadequate. For these cases,

SIGMA/W stresses may be used in SLOPE/W to compute the safety

factors.

Q U A K E / W R E S U LT S I N S L O P E / W

Earthquakes may generate inertial forces and excess pore-water

pressures affecting the stability of ground structures. SLOPE/W can use

both dynamic stresses and pore-water pressures from QUAKE/W to assess

stability and deformation following an earthquake.
